IMPROVEMENT IN HAIR-BRUSHES.

Specification forming part of Letters Patent No. 212,844, dated March 4, 1879; application filed y November l, 1878.

To all whom 'it may concern:

Be it known that I, FRANK A. FREEMAN, of Maplewood, county of Middlesex, State of Massachusetts., have invented an Improvement in Brushes, of which the followin g description, in connection with the accompanying drawings, is a specification.

This invention relates to brushes for use as hair-brushes for persons or for animals.

In other brushes having metallic pins or teeth held in an india-rubberor flexible backing, it has been customary to support the india-rubber and the inner ends or headed parts of the pins solidly upon the back ofthe brush.

The object of this invention is to produce a y so-called metallic brush 7 which shall more readily yield to the headand be more flexible and not so harsh.

To that end my invention consists in abrush .composed of metallic pins set in a sheet ot' india-rubber-or equivalent ilexible medium, the latter being so attached to the back or rigid part ot' the brush as to leave the majority of the pins and the india-rubber foundation for them, except a-t its ed ges, as shown in the drawings, unsupported by the brush-back, thereby leaving a free or air space between the back and india-rubber, and permit-ting the indiarubber to rise and fall freely from and toward the back.

Figure l represents, in longitudinal section, a hainbrush embodying one form of my invention; Fig. 2, a cross-section thereof, and Fig. 3, a modification, also in section.

The pins a a-nd india rubber or ilexible foundation are and may be as usual.

Instead of permit-ting the heads of the pins at the lower face or side of the india rubber sheet b to rest upon the brushlback c, as usual, the said flexible sheet is so supported or sustained upon or above the back c as to leave an open or air space, d, which will permit the pins and sheet at the central portion of the brush to move freely toward the back c when pressure is applied to the outer ends of the pins a.

To form the open or air space d, as in Figs. 1 and 2, the india-rubber sheet b, set with pins, is curved upward or convexed, as shown, and in said condition a sheet-holder, c, shown as a piece of cloth, is connected with the sheet b at its edges, so as to retain the outer face ofthe sheet b bent in its convex form. This sheet is then applied to the back-formin g portion of the brush, the cloth or other equivalent sheet-holder e between the 'outer edges of the sheet resting directly against the lnfushback, and holding the sheet bulged upward, as shown, away from the back.

Instead of this piece of cloth e, I might lace the edges of the sheet b with a thread and draw them somewhat together; and, if desired, I may set a sheet of rubber into a recess of smaller area, as in Fig. 3, when only the edges of the rubber sheet will rest upon the brush-back, and consequently a space, d, will be formed below the indiarubber.

In this way it is obvious that the pins are free to yield longitudinally and move toward and from the brushsback, and that the sheet b, except at its edge, is practically unsupported by the brush-back.

The back c may be of any usual material, and be iinished in any usual way.

The portions b c c may be united by a gluelike compound known as comps, or by india-rubber paste, or by pins, as shown at the leftof Figs. 2 and 3.

I claiml.' A brush having a back of sufficiently rigid material, in combination with a flexible sheet, of greater area than the back, secured to said back by being buckled up, so as to forni an inclosed air-space between the two, the said sheet being provided with metallic pins, substantially as and for the purpose described. y

2. In a brush, the india-rubber or ilexible sheet supported at its edges by the brushback, and held convexed above the said back, to yield and permit the pins to move longitudinally with the sheet toward the brushback, substantially as described.

3. The iiexible sheet b and metallic pins, combined with a sheet-holder attached to the edges of the sheet to bulge it outward away from the brush back, substantially as described.

In testimony whereof I have signed myname to this specification in the presence of two subscribing witnesses.

FRANK A. FREEMAN.
